The Biggest Little Record! The 45 RPM record was first introduced in 1949, but it wasn’t until the advent of rock 'n' roll that they became part of the scene. Elvis and his Sun Records releases changed everything and when Beatlemania washed ashore in the 1960s the 45 was a part of almost every American home with a teenager, every radio station and every bar with a jukebox. Today 45s ride a new wave of vinyl interest. With an easy-to-use format organized alphabetically by artists and featuring 80,000 records and labels covering nearly 70 years of music that changed the world forever, Goldmine 45 RPM Records Price Guide is the only identification and price guide on the market dedicated to "the little record with the big hole."
